:MEANS FOR DRIVING DYNAMOS FROM CAR-AXLES.

To all whom it may concern.'

Be it known that I, WILLIAM F. BoUcH, a citizen of the United States, and a resident of Depew, county of Erie, State of New York, have invented certain new and useful Improvements in Means foryDriving Dynamos from Car-Axles, of which the following is a specification.

My invention relates to improvements in means whereby dynamo electric machines may be efficiently driven from the axle of railway cars or the like. Many arrangements have been suggested for the driving of dynamos from car axles and the so-called shaft-drive has several advantages over the so-called belt-drive, especially in that the dynamo may be rigidly supported from the l car body which is cushioned on the trucks so that the dynamo is not subjected to the heavy jolts and jars to which the trucks are subjected. Also the positiveness of action and avoidance ofbelt breakage are advantages of the shaft drive. In the shaft-drive arrangements, however, where it has been proposed to'place a bevel gear upon a carl axle and drive from this a bevel gear on a shaft at right angles tothe axle, certain disadvantages have arisen,in that,` to get thenecessary reduction in gears, the second bevel gear has been so small withrespect to the irst bevel gear that the parts are subject to very great wear and tear and are apt to soon become loose and get out of order.

Also generally, due to wear, there is a cerdescription given below takenin connection Y tain relative lateral movement between the gears which causes a looseness of parts, great wear and. tear and a change of the relative speeds of the gears.

The main object f my invention is to overcome these disadvantages and provide a shaft-driven arrangement which is eiiicient and economical in operation' and construction and supported in a-simple and eii'icient manner. l i

Further, objects, advantages and features will more clearly appear from the detailed with the accompanying drawings which form a part of thislspecification and 'illus,

trate my improvements in a preferred form. I'desire it to be understood, however, that i many changes, modifications and omissions may well/be made without departing from the spirit and scope of my invention in'its broader aspects, and accordlngly I do not Specication'of Letters Patent.v

Referring to the drawings, 1 represents the body of a railway car provided at one end with a truck 2 having end sills 3 supported by the axle 4`carrying the usual wheels 5. Secured to the body of the car is a framework 6 rigidly carrying a dynamo of the parts shown in Fig. 3, partly in p electricl machine 7 having an armature adapted to be driven by a short shaft 9. adapted to slide in bearings 10 in the direc-`- tion of its axis, which bearings are rigid with the framework of the motor. The shaft silient metallic member 12 projecting from 9 carries a pin 11 adapted to engage a rea disk 13 carried rigid with the rotating armature of the dynamo, which member 12 is adapted to give way or break in case the dynamo should become stopped vfor any reason while the car is still running,- and thus prevent breakage of the shafting or other parts. p

Rigidly secured to the axle 4 is a fiat faced `gear 14 meshing with a'smaller flat faced gear 15 carried on a countershaft 16 having bearings rigid with the casing 17, which casing surrounds the gearing and is adapted to A,contain oil orgrease for lubricating the parts-in a well known manner. The casing 17 is Iat one end supported by the axle 4, the axle 4 running in bearings 18 therein, which bearings have a bushing vof cast brass 19 lined with a bearing'20 of Babbitt metal. The countershaf 16 is provided with similar bearings at 21. Thel bearings 18 are provided with oil or grease apertures 22 throughwhich oil or grease is supplied from the casing 17 into the bearings 18.

At one end the countershaft 16 is supported by ball bearings 23, and adjacent, y

the end sill 3 by means of a link 29 pivoted to an arm 30 extending from the sill 3 and a link 31 pivoted to the head28 with an intervening link 32 connecting these two links 29 and 31 and pivoted thereto at right angles to the pivots by which they are connected to the arm 30 and head 28, respectively. rllhe short shaft 26 is connected to l intermediate shafting 33 by means of a universal joint 34 and the shafting 33 is connected to the short shaft 9 by means of a universal joint 35. By thus providing a plurality of sets of reducing gears the gears 14 and 15 may be made more nearly of the same sizeand thegears 24 and 25 may be made more nearly of the same size so that there is less wear-and tear of them and they are less likely to get out of order. Also, by providing the intermediate gear 15 running on a countershaft parallel with the axle the casing may be permitted to slide slightly along the axle without in any way a'ecting the meshing of the gears 14 and 15, so that if the parts become worn so as to permit this slight shifting, there is no danger of the gears 14 and 15 binding or getting out of order. Also, by suspending the outer end of the casing from the sill 3 by meansof the pivotal'link connection 29, 32, 31, all strain is relieved from the parts and the casing with its contained gearing is supported so that it will hang freely and is not likely to get` out of order. At the same time the arrangement is simple and efficient in construction and the parts are easily replaced.

By providing a shaft 33, having a universal connection with the driving shaft 26,

and a universal connection with vthe dynamo shaft, the shaft 33, by means of the shaft 9,

f having a sliding movement with respect to 'A en the dynamo shaft, relative vertical and lateral movements between the dynamo and a.

axle, due to the swinging of the truck and the vertical movement of the car body on its springs, are provided for.
